Stress-Strain of Hotmix Cold Laid Containing Buton Granular Asphat (BGA) with Modifier Oil Base and Modifier Water Base as Wearing Course

摘要

Buton granular asphalt (BGA) is produced from natural rock asphalt. The employment of hotmix cold laid containing BGA with modifier oil base and modifier oil base can substitute hot rolled asphalt (HRA) construction in the remote and distance areas. Natural rock asphalt that deposited in Buton Island, Southeast Sulawesi in Indonesia is crushed to produce Buton granular asphalt (BGA). BGA and cold modifier were utilized to produce hot mixture that can be laid at cold temperature of 50^OC to 27^OC.The present study provides the information concerning the stress-strain pattern and compressive strength of hotmix cold laid containing BGA and Modifier Oil Base and Modifier Water Base at the storing and compaction time of 4 hours, 3 days and 7 days.
